GAS HEATER BURNER Filed Dec. 5, 1927 r 351 or any other suitablematerial.

Patented Apr. 21, 1931 UNITED s'rarns PATENT OFFICE WILLIAM B. BASTIAN,or LOS ANGELES, CALIFORNIA GAS-HEATER BURNER Application filed Decembergas and air are mixed in a mixing-bowlfrom which passages lead to formthe several jets.

This burner more nearly completely consumes the gas fed to it than anyother burner known. I have sought, however, to find ameans of increasingthe quantity of gas which such a burner will handle, and it is an objectof my invention to accomplish this purpose.

Further objects manifest in thefollowing description and in theaccompanying drawings illustrating a preferredembodiment of myinvention, and in which Fig. 1 is a perspective view of the gas burnerof my invention.

Fig. 2 is a vertical medial sectional view of the gas burner in Fig. 1.

Fig. 3 is a vertical sectional view taken on .30 the line 3-3 of Fig. 2.

Fig. 4 is a bottom plan view of the burner. Referring to the drawings indetail, a burner 9 of my invention is preferably formed of a body 10which may be of metal, bakelite A gas supply passage 11 is formed in thebottom of the body 10, this passage being tapped to threadedly receive agas supply pipe 12. The upper surface of the gas supply passage 11 isconical in shape. and air supply passages 13 and 14.

are bored transversely through the body 10 on opposite sides andequidistant from the vertical axis of gas supply passage 11.

Bored through the material intervening between the gas supply passage 11and the air inlet passage 13 is a gas jet hole 15 which diverges at asharp angle from the axis of the gas supply passage 11. Formedsymmetrically with the gas jet hole 15,. relative to the central axis ofthe gas supply and advantages will be."

passage 11, is asecond gas jet hole. 16 which communicates between thegas supply pas sage 11 andthe air inlet passage 14.

Gas and air mixture passages 18 and 19 are formed in the body 10 so asto communicate respectively with the air inlet passages 13 and 14 and soas to extend upward therefrom symmetrically on opposite sides of thevertical axis of the body 10 and turn at their upper ends so as toconverge toward each other. K

The operation of my burner is as follows Gas supplied to the supplypassage 11 through the pipe 12 passes through the holes 15 and 16 intothe air inlet passages 13 and 14 respectively. Here the jetting efi'ectof the gas discharged through the holes 15 and 16 draws air in throughopposite ends of the air holes 13 and 14 and mixes it with the gas asitpasses up the gas and air mixture passages 18 and 19. As the mixture isdischarged in the upper ends of the passages 18 and 19 and ignited itforms a very tall and hot flame 20 in which the gas is practicallycompletely consumed.

'Owing to the fact that a separate gas jet hole is provided, openingfrom the gas sup-' ply passage 11 into each of the air inlet passages 13and 14, which in turn separately and individually supplya mixture of airand gas to the mixture passages 18 and 19, an extremely large volume ofgasmay be mixed and directed from the upper ends of the mixture passagesto form the flame 20. As aresult of this fact, in combination with theextremely compact structure of the burner due to its being formedcompletely by a single body of material, an unusually large amount ofgas can be completely consumed by the single burner 9, thus making itpossible to reduce the number of burners used to a small fraction of thenumber previouslyrequired for a given heating purpose.

With particular reference to Fig. 2, it will be noted that therespective gas jet holes15 and 16- are bored at an angle to thel0ngitudinal axis of their associated mixture pas? sages18 and 19 sothat the gas jetting fromthese jet holes will discharge against a wallof the respective mixture passages, it being evident that the gas streamwill thus be immediately broken up, its particles rebounding from saidwall and across the mixture passage in various directions to again smashagainst another portion of the wall of said passage and again rebound.This more or less zigzag clash and rebound travel of the gas will causea thorough intermixing of the gas and air throughout the entire area ofthe mixture passages, and is a very advantageous condition which willnot be present in a similar burner having its gas jets discharging alongthe axes of the mixture passages, it being evident that in event of agas jet axially aligned with a mixture passage the jet merely 1609 anaxial path through said mixture passage, leaving the rest of the area ofsaid passage practically undisturbed.

I claim as my invention:

1'. A gas burner comprising: a body, there being formed therein a gassupply passage, gasand air mixture-conducting passages ten minatiiigwith their axes converging toward each other, air inlet passages. eachconnecting with one of said gas and air mixture passages, and gas etholes, each connecting said gas supply passage with one of said airinlet passages and arranged to discharge its jet toward a wall of therespective mixture passage.

2. A gas burner comprising: a body, there being formed therein a gassupply passage, gas and air mixture-conducting passages terminating withtheir axes converging toward each other, air inlet passages, eachconnecting with one of said gas and air mixture passages and openinginto the atmosphere at its opposite end, and gas jet holes, eachvconnecting said gas supply passage with one of Said air inlet passagesand arranged to discharge its jet toward a wall of the respectivemixture passage.

3. A. gas burner comprising: a one piece body, there being formedtherein a gas supply passage, gas and air mixture-conducting passagesterminating with their axes converging toward each other, air inletpassages.-

e'ach connecting with one of said gas andair mixture passages, and gasjet holes, each connecting said gas supply passage with one of said airinlet passages and arranged to discharge itsjet toward a wall of therespective mixture passage.

4. A gas burner comprising: a one piece body,there being formed thereina gas sup ply passage, gas and air mixture-conducting. passagesterminating with their axes converging toward each other, air inletpassages, each connecting with one of said gas and air mixture passagesand opening into the atmosphere at its opposite end, and gas jet holes,each connecting said gas supply pas sage with one of said air inletpassages and arranged to discharge its jet toward a walli of therespective mixture passage.

5. A gas burner comprising: a body, there bein formed therein a single,tapped gas supply passage, gas and air mixture-conducting passagesterminating with their axes converging toward each other, air inletpassages, each connecting with one of said gas and air mixture passages,and gas jet holes, each connecting said gas supply passage with one saidair inletpassages and arranged to discharge its jet toward a wall of therespective mixture passage.

A gas burner comprising: a one piece body, there being formed thereina single, tapped gas supply passage, and air mixture-conducting passagesterminating with their axes converging toward each other, air inletpassages, each connecting with one of said gas and air mixture passagesand opening into the atmosphere at its opposite end, and gas jet holes,each connecting. said gas supply passage with one of said air inletpassages and arranged to discharge its jet toward a wall of therespective mixture passage.

7. A gas burner comprising: a one piece body having a gas supplypassage, a gas and air mixture-conducting passage, an air inlet passagebetween said supply passage and said mixture passage, and a gas jet holecommunicating with said supply passage and adapted to discharge a jet ofgas across said air passage and into said mixture passage, said gas jethole being angled relative to the axis of said mixture passage to directsaid jet toward a wall of said mixture passage.

In testimony whereof, I haveliereunto set my hand at Los Angeles,California, this 30th day of November, 1927. v V
